Serial.print("tock"); motor.run(BACKWARD); // the other way delay(10000);

Serial.print("tack"); motor.run(RELEASE); // stopped delay(1000);}

but motor goes not work. When i connect motor directly to battery module, he work. But when motor connected to shield, he does not work, but sometimes it makes a noise. I use the voltmeter to test a voltage. On the shield's ext_pwr 8V, on the unplugged terminals 6v, but when i plug in motors - voltage drops to 0. Why voltage drops when i connect the motor? I tried to connect a new batteries, and increase the number up to 8 pieces(AAx8), but no effect. May be my shield has broken?Please help me fix this trouble...
